- others skilled in the art to which it apper- I tains to make and use the same.

This invention relates to new and useful improvements in differential, transmission and clutch housings and more particularly to assembling such housings so that when secured together they form a single or continuous unit which prevents relative movement of the housings in relation to each other that obviates any danger of the parts confined therein from becoming out of alinement. 7 I l I 7 Another object of this invention is the provision of a male and female connection or joint between each pair of housings which lessens the strain on the. fastening means between said pair of housings and makes it possible to keep all units in better operating alinement than was heretofore possible and reduces the space on the tractor or motor vehicle required to. accommodate such structure. a

A further object of this invention is the provision of means whereby the centers of the openings in the differential, transmission and; clutch housings and rear pilot opening for the worm shaft or the. difi'erential. are arrangedeccentrically to each other so that the'forces created by the, driving or braking action, that have. a tendency to rotate one housing about the other. are con.- sumed by the flanges and walls oi the openings in the housings, thereby relieving the strain on the tasteningmeans between said housings. 7

With these and other objects in view as will becomemore apparent as the description proceeds, the invention consists in certain novel features of construction, combinzition, and arrangement of parts as will be hereinafter more fully described and claimed,

Specification of Letters Patent.

Application filed February 6, 1920. Serial No. 356,746.

For a complete understanding of our inventlon, reference is to be had to the following description, and accompanying drawings, in which Figure 1 is a vertical sectional view illustrating assembly of differential, transmission and clutch housings with differential. transmission and clutch located therein,

Fig. 2 is a vertical sectional view of the housings assembled with the difierential, transmission and clutch removed,

Fig. 3 is a diagrammatical view, illustrating the openings in the housings and the rear pilot bearing opening in relation to each other. I

Referring in detail to the drawings, the numeral 1 indicates a differential housing which has a bowl or enlarged portion 2 provided with an opening 3 in its front wall to receive and be closed by the. rear end of a transmission housing 4:. The differential housing 1 or the bowl 2 at its rear end is provided with an opening 5 to receive a rear pilotloearing 6 which rotatably supports the rear end of a worm shaft '6 of a diflerential 8,located in the bowl 2 of the difierential housing 1 and permits said w'ornr shaft 7 to extend into a brake housing 9 formed integrally with the differential housing 1 so that a brake mechanism 10 can operate on the rear end of the. worm shaft. The center of the opening 5 is. located eccentrically to the center of the opening 3 as illustrated in the 'diagrammatical view.

The transmission housing 4 has its rear end closed by a rear wall 11 which abuts the flange 12about the opening 3 of the difierential housing 1 and is secured thereto by fasteners 13. An annular flange 14 is formed on the wall 11 and pilots or fits in the opening dforminga male and female connection between the tmnsmission and differential housing 1. n v A hanger 15 'sgformjd integrally-with the flange 14 and extends into the bowl 2 of the differen ial housing 1 and rotatably supports the differential 8 andhas a bearing opening 16 in its rear portion and in alinement with the opening 5 and receives a bearing 17 v that rotatably supports the worm shaft 7 The forward end of the worm shaft 7 is journaled in a bearing 18 located in a bearing opening 19 formed in the rear wall 11 of the transmission housing 4 and which is in horizontal alinement with the bearing opening 16 of said hanger thereby 7 is formed on the forward end of the trans I forward end of the mission housing 4 and defines 21, the center of cally to the center of the opening 3 and also the opening 5. A clutch housing 22 has its rear end closed by a wall 23 which is secured-to the flange by fasteners 24. An annular finge 25 is formed on-the Wall 23 of the clutch housing 22 and pilots or fits in the opening 21 of the transmission housing 4. bearing opening 26 isfornied in the wall 23 and is in horizontal alinement with the opening 19 of the rear wall 11 of the transmission housing 4 and said bearing opening 26 receives a bearing 27 that rotatably supports a power shaft 28. The

an opening fined within the clutch housing 22 and has a clutch 29 associated with a fly wheel 30 on the crank shaft shown). 7 l r it The power shaft 28 extends rearwardly into the transmission housing 4 and is adapted to be connected to the worm shaft 7 through a transmission 32 that forms subject matter of a co-pendingapplication se' rially numbered 356,749 and filed Feb. 6, 1920. r

.It is to be noted that the worm shaft7, power shaft 28 and crank shaftof the motor are in horizontal alinement, obviating the employment of universal joints and like connections which are necessary when the engine is located in a different plane from that of the power shaft of the transmission and the driven shaft of the differential.-

The opening 33 of the front end of the 1 clutch housing 22 has its center located eccentrically through'the opening 3 of the differential housing 1 and the opening 21 of the transmission housing 4, and an annular flange 34 is disposed about the opening 33 and fitsfor pilots in therear'end of the: crank case orhousing 35 0f theengine '(not shown) and the crank case-35 has an annular flange 36 which is secured to the front end of the clutch housing 22 by fasteners 37, the

centerof the opening 33 is located concentrically to the center of the opening in the differential" housing 1." I y I "The opening 3 in the differential housing, the opening 21 in the transmission housing I and the opening 33 in the clutch housing heat have an eccentric arrangement relatively, whereby to place upon the and 34'and the walls of said openings, the entire burden of holding the housings against any relative rotation under the rothereto by the ative forces transmitted the idle gear which is located eccentri power shaft'28 is con- 31 of an engine (not each other.

flanges y Y on certain end walls of said gearing during either a driving or braking action thereof. This prevents any lateral forces froiii-being placed upon the fastening elements which are employed to connect the housings together. V V

The top-wall of the transmission housing 4' is provided with an opening 38 to permit 39 of the transmission 32 to project outwardly of'said housing and be received in a power take-off housing- 39 having a power take-ofi' 40 which with the power take-off housing matter for a co-Pending power take-oif housing 39 transmission housing 4 by application. The

fasteners 41 and 'is also secured to the topof the clutch housing 22 which aids in securing the clutch and transmission housingtogethen V The lower portion of the clutch housing 22 is provided with a hand opening'42 so issecured to the 39 forms subject that the clutch 29 can beadjusted and which 7 is closed by acover plate 43.

While we have shown-and described the preferred embodiment of our invention, it

that m nor changes inwill be understood construction combinatiomand arrangement j of parts may be ,made. without departing from the spiritan'd scope of the invention as claimed. I 7
